Application filed July 16, 1909. Serial No. 507,918,

To all whom t may concern.'

Be it known thaty l, BENJAMIN F. Ban Lows, a citizen ot the United States, residing at Cleveland7 in the county of Cuyahoga and State of hio, have inventedy a certain new and useful linproven'ient in Spacer Selecting and .Releasing iil'echanism, ot which the following la full7 clear, and exactdescription.

This invention is intended to be used a part ot' justifying mechanism similar to that which terms the .rihjectI matt-er ot the Bellows Patent No. 797.549.

It, relates particularly to the mechanism .for selecting and releasing the justityine spacers, and may, with very slight modihcations ot the associated mechanism7 be substituted tor the spacer selectingF and releasingr mechanism oi that patent. lt is, however, more particularly an improvement in the spacer selecting and releasing mechanism which torms the subject. matter o t'A the Bellows Patent No. 895,231.

s described and shown in the iirst named patent7 the spacers to be selected and released are stored in vertical Channels. These cliannels are arranged in groups constituting` magazines, and each magazine has a single discharge mouth, through which spacers released trom any ot its channels are delivered into a tube bywhich the spacers are conveyed and delivered into an as semhled line ot matrices. In that patent three` vertically movable rods are siown. One rod is moved` vertically a definite distance every time a temporary spacer is added to the line. Another vertically movable rod is theorie, which, alter an assembled line has reached justifiable length is given v rtical movement every time a ma! tris is added to the line, which is proper tionate to thc width ot the matrix so added. The third vertically movable 'rod is that which is `iven a vertical movement alter the other two rods have been moved as retpiired` and the line has been completed, whereby the spacer releasing mechanism is caused to operate so as to release the selected permanent spacerswthat is to say, we space from each magazine whose corresgmmlinf.;` tnbc has been put into the asscm blinglinw the aggregate width of the spacers so released being equal to the line shortage. lt' the mechanism constituting the present invention is to be usefully employe .moving endwise in said bearings.

as a part of a machine for justifying lines of matrices or type, (and that'is the purpose tor which it is intended) it must l I associated with mechanism having `Lne same functions and substantially the same mode.

ot operation as the three vertically movable .rods referred to, Wherefore the upper ends ot said rods are shown in the drawings and are designated respectively 84, 90 and 11.5. lt is to be understood, however, that the mechanism constituting the present invention will select and release from their" magazine channels a great variety of combinations of spacers, irrespective ot the means employed tor moving the parts which control the position ot the selecting cylinder.

The present invention will now be., described, reference being had to the accompanyinfr drawings, in Which- Figure 1 is a plan view ot the presentinvention. Fig'. 2 is arear .elevation thereof. Fig. 3 is an end elevation on the left side of Figs. 1 and 2; and Fig. l is a vertical se@ tional view in the plane indicated by line fl--l on Fig. 2.

The selecting cylinder 14 is secured to a sha tt 16 which is mounted in suitable bean ings 18 so as to be capable ot rotation and ot In the surface ot' said cylinder are formed a number ot holes 13, which are placed at the intersections of imaginary longitudinal lines and circumferential lilies on the surface of said cylinder, as indicated by dotted lines in Fig. 1. The number of longitudinal rows of holes is equal to the number ot teeth in a ratchet wheel 30 iixed to the said shaft; and this, when this mechanism is used in connection with such justifying mechanism as is shown in the patent referred to, is equal to the number ot units ot' shortage which' can be ilied outy in the line by the various combinations ot spacers which can be released trom the spacer channels. These holes will also be arranged in a `treaty number ot circumferential rows. lt, for example, the spacer channels are grouped in six magazines, the number ot circumterential rows ot' holes upon the cylinder will be six times the number ot spacer channels ein` ployed. Only a ten' ot these holes are shown: and no attempt has been made to show the precise location ot those which are shown. The holes may be disposed upon the I surface ot this cylinder in precisely the same cured to arm (3l.

u with the arms on the star said arms in aline'ment.

'arms (Sl in a reverse with the lever 60. The engagement of the plunger with vthe ratchet very accurately' brings the cylinder into the correctl position, provided it was only a little removed from that position. The cam 50 will be turned into the releasing position by the, action ot pawl 45 on arm 60. The selected pallet levers, that is to say, those whose rods fl() are beneathholes in the cylinder,`will be then severally operated by their spring plungers 5l and one space 1 will be released from each associated channel 9.

By reversing the direction of movement of the rods 84, and 115 all of the parts will be returned to their normal positions-that is to say, rod 41 will be drawn down. and thereby the cam is permitted lo roel: haekward and is so rocked by the action ot' spring 56, thereby drawingilown vthe elevated tail pieces ofithe pallet'levers. vlts backward rocking mot-ion is limited by the engagement of an arn 55 thereon with the bar 5. The plunger 22 is simnltaneously drawn downward by the action of arm (lll on pin 23; the stepped wedge (ST is moved downward, and thereby, since the steps thereon `ioin each other by' each inclines` the sha'lt l6 is moved endwise to its initial positionA The rack 2S is moved upward. and thereby shaft lll is turned bach to its normal position.- v

Two adjunctive features ot' construction are shown. One is Jfor the pin-pose ol securing the alinement of all of the star wheels. This consists ofta frame comprising two lcvers 6l, which are looselylhung on the lam shaft, and a bar G3 which extends between and is connected with .said levers. and normally lies over' and in contact with a horizontal arm on each star wheel, the iframe being normally held in this position. by springs (32. These springs are ol the rat* trap variety, and one end of each spring enf-aiies with a radial arm .35 fixed to the cam and the other end engages with a pin (SlL se i lVhen the cam is in its normal position, these springs are pnt under such tension that the arms (3l "will be swung,r so that the rod G3 will engage with and apply a light but suliieient torce to tie arms on cachot the star wheels so as to hold lVhen the am is turned to the releasing position, the arms 55 will engage the pin Gl and slightly rock the direction whereby the rod 63 will be moved so tar away trom the star wheel arms, that the star wheels may turn. When the cam rocks to its releasing;r

position, these levers are rocked, and this,

rod withdrawn so as to permit the star wheels to turn, but whenrthe cam returns to its normal position the bar 68, engaging; wheels brings said star wheels to correct position. e

Another feature consists of a plurality of weighted pawls l0, one associated with each star wheel. One end ot each pawl lief in. the path ot` the arms on the star wheel. When the star wheel is turning in the direc tion to release a spacer, an arm litts the pawl and passes it readily, but, it by mischance the stary wheel be turl'ied in the, rc verse direction, this pawl by engaging with an arm of the star wheel limits the extent ot such movement so that no harm will be done.
